This invention relates to a wire cutting machine adapted to rapidly cut wire into given lengths ywhile being continuously fed into themachine.

Heretofore it has been necessary to arrange the wire feeding mechanism so that the feeding will be interrupted while the cutting process is in operation,v which not only necessitates the -use Vof complicated mechanism but prevents the rapid action of the machine thereby causing a loss of' time in its operation.

The main object of this invention is to provide a cutting machine which will permit the continual feeding of the wires therein without interruption, cut the wire in given lengths and discharge it for convenient handling. This is accomplished by means of an intermittently rotated cylinder having a plurality of wire receiving grooves in its face into which the wires are successively fed and cut.

Another feature of the invention is the means for actuating the wire carrying cylinder so that it will be intermittently rotated a partial revolution when actuatedv by the wire being fed into one Vof the grooves of the cylinder so that it ywill be cut into lengths and discharged therefrom.

Still another feature of the invention is the adjusting means for taking up any play in the gears due to the wear of the teeth or in further accurately adjusting the wire carrying cylinder so that the grooves therein will be in proper position for causing the mechanism to be operated which means will be hereinafter more fully .shown and described. uThe full nature of the invention will be understood from the accompanying drawings and the following description and claims: V-

lin4 the-drawings there is shown a machine having a wire4 carrying cylinder 10 supported at one end by the stud l1, see Fig. YI0, which extends through andV is revoluble in a sleeve' l2 and bearing 13, supported on' the basejlt. The other end of saidcylinder is supported in a sleeve l5 and bearing 16 mounted on the base 17, see Fig. e. Y.The bases iliand l? are rigidly secured together by a connecting rod 18. The cylinder l0 is provided with v longitudinal grooves V19 through which the wire is adapted toeXtend. At the feeding end of the cylinder theV grooves i9 open into outwardly' tapering channels 20 which are best shown in the en? larged, view of said cylinder as shown in Fig. l1. ligidly mounted on the stud llso as to revolve .with said cylinder there is af pair of oppositely extending cutters 21,V see so as to litin the coils, thereby making a clean cut andnot changing the shape of the wire. as shown in'Fig. 10 s o as to pass between the The wire 23 is fed into the machine cutters 21' and 22 and extend into one ofthe f channelsl 2O and into the groove 19 corresponding with the channel at the end of the cylinder and passing therethrough until it engages the stop rodt', see Figui, which sets the rotating mechanism in operation to give aY partial revolution tothe cylinder as will Vbe hereinafter described, therebyV causing thecuttcr to pass thev cutter 22 at a high rate of speed; and cutting oif I which is provided with a disk clutch 40 havthe length of wire extending therefrom to said stop rod. As soon as said knives have passed each other, which is substantially instantaneous, the wire which is being'continually fed therein will begin to enter the follow/ing channel 2O in said cylinder while it is moving; VAs it is necessary that the wire be detained for an instant while the cutters are passing each otherk and as the feeding is continuous the wire will bow upwardly inthe feeding troughk 20a extending from the coiling machine (not shown) until the cutter 21 has passed out of the path of the wire, when, in'view of the springy nature'of the vwire, it will immediately straightenr out and enter'the channel 20 of the next'succeeding groove 19, and in view of the taper of one wall ofthe channel 20 the4 wire will move through the channel and enter the groove without contacting the wall of the l channel. It4 will, therefore, be'seen from the foregoing that a continuousfeedng'of the wireis permitted dueto the out-x wardly" tapering channels vand the springy naturel of the wire, and the'mean's which will 1 be hereinaftery described for y'causing a par.` tialrot'ation of the vv-ire carryingcylinder and the cutter.HV For preventing the wire from escaping the upper channel and recess there iis' provided a guard 25', vsen'ii-'circular in cross section which covers theupper side of saidfcylinder Yand is supported at its endsY by the brackets 26 and 127.v

The following -mechanism drives the wire carrying cylinder in vits intermittent semi-y revolution: l y

Loosely mounted on the cylinder 10 there is a cam shaped collar 27 which is pivoted on the yoke28, and is adapted to be moved longitudinally lof said Vcylinder bythe stop rod 24 which has a block adjustably secured thereto by the set screwl'129. By adjusting the block upon the stop rod 24 relatively to said collar any desired length of wire may 1 be cut. When the Wire 23 engages the stop which are supported on the base 17. Loose# ly mounted on said shaft isa fly wheel 39 ing a plurality of circumferential rholes or openings 41, as shown in Fig. 7. The disk clutch 40` is in such a position that the'holes `41 may` register with the pin 34 as shown in Fig: 5, so that when the pin is engaged with one of thev holes 41 the rotating fly wheel will cause the shaft 36 to rotate. The pin 34 is thrown into engagement with the y clutch member 40 by the movement of the arm 30, which upon moving the plunger 32 fromengagement with the block 33 permits the pin 34 to be drawn forward by the spring 44 which is secured at one end to the sleeve 35 and at the other end to a dowel pin 45 secured in the pin 34, said dowel pin entering a slot provided for that purpose in the sleeve 3 5. The pin 34 is thrown out of engagement with the clutch member when the Y arm30 .causes the plunger 32 to return to .I the position Vshown infrFig. 6 so that its curved side will engage'the beveled end of` the block33, as shown in Figj12, which would force said block rearwardly and draw'` e the l'pin fromwthe elutch ,member 40 and at;

the same timeengage'V said pin as shown inf Fig. 6 and prevent the further revolving movement of the sleeve 35 and shaft 36. Y.

Mounted on theinner end of the shaft36 and keyedthereon is a beveled pinion 47 inl position'toY` mesh with Athe* beveled'y gear. v48

which is loosely mounted on the lCylinder 410.A 'The gear 48"'i's locked to the Acylinder`10KV through ya hub vmember-.149 'which is lkeyed thereto, which hub'has alflange 570 provided with' a plurality of holes 51 las shown in Fig. 8. The gear 48 is vprovided with, a

" plurality of holes 52 and has a greater numlber of holes thanthe number'of holes in the flange 50. The hub y40 andthe gear 48 are then loeked together by inserting Ya dowel pin 53 .throughthe registering holes 51 and Y52, by means of which any adjustment mayy be obtainedbetween the cylinder v.10 and the the cylinder 10, said cam having faces 35@` "thereon, which are so'positioned that oneof themwillengagethe c'ammed face 27 a lof Ithe f collar 27,' as soon vasthe sleeve 35 and pin 34 have rotated a sufficient distance to move out.

of thepa'thtof the plunger 32, thus moving the vcollar`e27 and parts controlled thereby,

inwardly and again positioning the plunger 32 in' the path of the blockl33fand pin vAs soon as the sleeve35 hasy made a com.- 'plete revolution the beveled fa ce of the block 33 will engagethefroundedface of the "plunger 32, said lplunger withdrawing the pin 34'jand stopping the rotation ofthe cylinder 10'.:` Y

The operation of the machine is as follows:

The Wire 23 is, fed valong the slot 19 until it engages the .stoprrod 24, which moves. the:

Collar 27 forward causing the shaft v29 to turn whereby the plunger 32 will be drawn from in front of theblook 33 vwhich will per! mit the spring'44 to draw the pin 34 into one of the'holes4-1in the clutch 40 which Ais l keyed to the continually moving wheel 39. This will'then loc'k'said fly wheellwith the sleeve 35AwhivehV iisfekeyed on the shaft 36 and rotate the pinion l?, and if the cylinder is provided with but two grooves 19, 'as shown, the ratio of the

gears

17 and 18 will be such that the gear 17 will make one coinplete revolution while the gear 48 is making but a half revolution, but if a greater number of grooves are provided, the ratio between the two gears will be proportioned accordingly. Pis the gear 1S is locked to the clutch i9 keyed on the cylinder 10, the cylinder 10 will be given a partial revolution with each revolution of the gear a7, in this instance a half revolution, thereby causing the cut-

ters

21 and 22 to engage each other and cut off the wire which will pass on around with the cylinder and drop from the groove 19. The instant the wire is cut the following length of wire will be fed into the next succeeding channel 20 and subsequently through the groove 19 to engage the stop rod in said groove and perform another operatioii of the machine. Vlhen the cylinder has started on its partial revolution the cam 55 will engage the collar 27 and force it back into its original position which will cause the arm 30 to move the plunger 32 into the position shown in Fig. 6 so that the block 33 must engage it and force it rearwardly, thereby drawing the pin 34 from the hole 4-1 in the clutch 40 and releasing the fiy wheel, said pin at the same time engaging the plunger 32 and preventing the further movement of the shaft 36, gears, and cylinder 10, which parts must then come to a sudden stop.

In order to adjust the cylinder 10 to its proper position the pin 53 may be removed so that the cylinder is free to be turned to any position and then locked with the gear 48 by reinserting the pin 53, and if the gear teeth should wear so that the proper position could not be obtained in this manner the corresponding holes 51 and 52 through which the pin 53 extends may be adjusted so as to compensate therefor.
